The affected endpoints return presigned file URLs and enable destructive or duplicative actions without verifying that the requester is a member of the targeted workspace. This enables cross\u2011tenant data exposure, data deletion, and persistent exfiltration of files into an attacker\u2011controlled workspace."}], "lastModified": "2026-07-23T15:29:23.713", "sourceIdentifier": "cret@cert.org"}
